Definitions

  • the present invention relates to a device for underrun protection of vehicles. More particularly, the invention is primarily intended to be applied to heavy cargo vehicles, in particular for preventing passenger vehicles from underrunning the cargo vehicle in the event of a head-on collision.
  • ground clearance is normally on the order of about 40 to 50 cm.
  • the cargo vehicle can be designed with a lowered front, i.e. a front in which the ground clearance is so low that there is no room for a passenger car to slide under the cargo vehicle and be pinned between the cargo vehicle and the road in the event of a collision.
  • a solution counteracts the above-mentioned desire for high ground clearance in order to facilitate driving on uneven terrain. A lowering of the ground clearance is thus not possible for many kinds of cargo vehicles.
  • Another solution to these problems is to provide the cargo vehicle with special underrun protection in the form of a reinforced structure, for example in the form of a horizontally arranged beam element in the front of the cargo vehicle.
  • a reinforced structure for example in the form of a horizontally arranged beam element in the front of the cargo vehicle.
  • a reinforced structure can be so arranged that it becomes energy-absorbing, whereby the structure absorbs energy when strained. This further decreases the risk of serious injuries in the case of a possible collision.
  • German patent document No. 4,103,782 A known underrun protection for cargo vehicles is shown in German patent document No. 4,103,782.
  • This underrun protection comprises a shock-absorbing element which is arranged under the front bumper of a cargo vehicle.
  • the shock-absorbing element can be arranged at a certain angle relative to the road.
  • the bumper In the event of a collision with a passenger car, the bumper will be affected with a certain force, which will cause a link system to move the shock-absorbing element to a position which prevents the passenger car from sliding under the cargo vehicle.
  • This new design in principle provides good protection against underrunning of the passenger car, it has a drawback in that it comprises a large number of moving parts, which makes it unnecessarily complicated, and it creates a risk of degraded function.
  • This solution additionally offers little possibility of directing the energy absorption in a controlled manner in the event of a collision.
  • the object of the present invention is thus to provide an improved underrun protection for cargo vehicles, which provides a reliable function, and which meets the demands made on energy absorption.
  • an object of the present invention is to provide an underrun protection which provides a controlled energy absorption during stress.
  • the apparatus comprising an impact member and an energy-absorbing member mounting the impact member to the frame at a location corresponding to the expected point of impact of a force generated by a collision, the energy-absorbing member including an upper portion connected to the frame, the upper portion of the energy-absorbing member comprising a hardened portion of the energy-absorbing member, a lower portion comprising a non-hardened portion of the energy-absorbing member, and a boundary area between the upper portion and the lower portion, the boundary area comprising a weakened area of the energy-absorbing member whereby upon the impact the energy-absorbing member is adapted to pivot about the weakened area for deformation of the energy-absorbing member thereabout.
  • the weakened area has a predetermined configuration whereby the weakened area deforms only when impacted by a predetermined impact force.
  • the energy-absorbing member is adapted to pivot about the weakened area substantially longitudinally across the vehicle.
  • the energy-absorbing member comprises a console extending substantially vertically with respect to the vehicle, and the weakened area of the console comprises an aperture extending through the console.
  • the energy-absorbing member comprises boron steel.
  • the impact member comprises a crossbeam extending substantially across the front of the vehicle.
  • the apparatus includes a counteracting member mounted on the vehicle adjacent to the energy-absorbing member whereby upon a predetermined degree of the deformation the energy-absorbing member contacts the counteracting member.
  • the counteracting member comprises a spring attachment to the vehicle.
  • the present invention is intended for vehicles which comprise a frame structure and an impact element which is arranged on the vehicle in a position which corresponds to an expected force strain in the event of a collision.
  • the present invention also comprises an energy-absorbing element which connects the frame to the impact element.
  • the present invention is based on the energy-absorbing element being shaped with a weakened portion, which essentially constitutes a pivoting joint for deforming or bending of the element during such strain.
  • the energy-absorbing element is shaped so that it is only deformed during energy absorption if it is affected by a force which exceeds a predetermined threshold value.
  • This threshold value can be chosen according to current legislation.
  • the invention comprises a counteracting element, preferably in the form of an existing spring attachment in the vehicle.
  • the energy-absorbing element can come into contact with the spring attachment, whereby extremely large forces are absorbed.
  • the present invention can thus withstand larger forces than that of the planned legislation, without the risk of underrunning occurring.
  • FIG. 1 is a side, elevational, partially schematic view as to how the present invention can be arranged in a cargo vehicle;
  • FIG. 2 is an exploded perspective view of the main components according to the present invention.
  • FIG. 3 is a side, elevational view showing the function of the present invention.
  • FIG. 1 is a somewhat simplified side view, which shows a cargo vehicle 1 which is provided with an arrangement according to the present invention. This figure also shows a passenger car 2 . From the figure, it can be seen that a possible head-on collision between a passenger car and a cargo vehicle could lead to the passenger car being pinned down between the cargo vehicle and the road, which might cause serious injuries to those travelling in the passenger car 2 .
  • One of the main objects of the present invention is to prevent such situations from arising.
  • the cargo vehicle 1 is, in a conventional manner, provided with a frame which comprises two longitudinal frame beams, of which only one frame beam 3 can be seen in the drawing.
  • the frame beam 3 essentially extends in the longitudinal direction of the vehicle 1 , up to its front.
  • there are two chassis consoles 4 fixedly arranged at each frame beam 3 to be more exact at the front of each frame beam 3 .
  • the drawing shows only one of the chassis consoles 4 .
  • energy-absorbing means are provided in the form of two additional consoles 6 (of which only one console can be seen in FIG. 1) which are attached to both the frame beam 3 and the chassis console 4 , and which connects these elements to each other.
  • the consoles 6 which will be described in more detail below, constitute an impact element in the form of a beam 7 which extends essentially horizontally across the longitudinal extension of the vehicle 1 .
  • the crossbeam 7 has an essentially square (alternatively rectangular) cross-section and is arranged at a height over the road which corresponds to a predetermined ground clearance, preferably from about 35 to 40 cm.
  • Each of the frame beams 3 is additionally connected to a molded console, which constitutes a spring attachment 9 for a spring 10 .
  • spring 10 constitutes a part of the wheel suspension of the cargo vehicle 1 .
  • the spring attachment 9 is essentially arranged in line with the energy-absorbing console 6 , i.e. as seen in the longitudinal extension of the cargo vehicle 1 .
  • the present invention functions in the following manner.
  • the crossbeam 7 will be affected by a large force F.
  • This force F will propagate to each of the consoles 6 , which in a controlled manner can be deformed so that the force can be absorbed.
  • the passenger car 2 is prevented from sliding in between the cargo vehicle 1 and the road.
  • FIG. 2 is an exploded perspective view, which in a somewhat simplified manner shows the design of the crossbeam 7 and the energy-absorbing consoles 6 .
  • This drawing only shows one of the consoles 6 and part of the crossbeam 7 .
  • Both of the consoles are, however, arranged in the same manner.
  • Each of the consoles 6 is preferably manufactured from boron steel, and is arranged by means of a bolted joint in an attachment 11 , close to the end 12 of the crossbeam 7 .
  • each console comprises an upper section 13 , which preferably consists of a rigid attachment portion which is intended to be attached to each frame beam 3 (of which only one frame beam can be seen from FIG. 2) by means of a bolted joint.
  • the high degree of rigidity of the upper section 13 is preferably obtained by the hardening of this part.
  • the attachment to the frame beam 3 is made by means of the above-mentioned chassis console 4 , which is shaped with a cross section which essentially looks like the letter “h”.
  • the upper part of the console 6 is moved into the chassis console 4 as shown by an arrow in FIG. 2 .
  • the console 6 and the chassis console 4 are arranged at the frame beam 3 by means of (not shown) through-going screws, which extend both through the consoles 6 and the chassis console 4 .
  • the crossbeam 7 When exposed to a force F, the crossbeam 7 will be affected so that force propagates to each of the consoles 6 . If the force is sufficiently large, the consoles 6 will be deformed and bent backwards.
  • the midsection of the console 6 is shaped with a waist 14 , which comprises a hole 15 , which constitutes an area of weakening at which the console 6 can be bent when exposed to a force.
  • the lower part of each energy-absorbing console 6 is shaped as an oblique portion 16 , whose form is adjusted to each of the attachments 11 of the crossbeam 7 .
  • FIG. 2 does not show the spring attachment 9 or the spring 10 (see FIG. 1 ).
  • FIG. 3 is a side view of the arrangement according to the present invention, which illustrates the fact that the energy-absorbing console 6 is fixedly arranged at the frame beam 3 by means of a bolted screw 17 in the upper section 13 of the console 6 . Additionally, the console 6 is connected to the chassis console 4 by a further bolted joint 18 . The chassis console 4 is, in turn, also connected to the frame beam 3 . In the event of a collision, the crossbeam 7 will be affected by a force F, which propagates to the energy-absorbing console 6 .
  • the console 6 is dimensioned to withstand the stresses which correspond to a pressure up to a predetermined threshold value (for example a pressure of 16 tons straight into the crossbeam 7 ).
  • the bolted joint 18 between the console 6 and the chassis console 4 is dimensioned so that it is torn apart in case of stresses which exceed the threshold value.
  • the energy-absorbing console 6 is dimensioned so that, in the event of such large forces, it will collapse and be deformed through bending while absorbing energy.
  • the hole 15 is arranged to define a weakened part at the waist 14 of the console 6 . This weakened part forms a rotational joint for the bending of the console 6 . When affected by this force, each of the consoles 6 will be bent backwards in the direction of the position shown by broken lines and with reference numeral 6 ′ in FIG. 3 .
  • the consoles 6 Since the upper section 13 is hardened and extremely rigid, and since the waist 14 has been provided with the properties of a softer material, the consoles 6 will be deformed while absorbing energy in a very controlled manner. When affected during a possible collision, the waist 14 will bend somewhat like a hinge around the rotational joint which is formed in the area around the hole 15 , while the lower part of the console 6 will be displaced rearwards in the vehicle.
  • This controlled process is primarily obtained by manufacturing the console 6 from boron steel, and by hardening the upper section 13 . This, among other things, causes a very sharp transition between the two parts of the console 6 which have different material properties after hardening.
  • the portion of the console 6 which is hardened is shown in FIG.
  • shaded part 19 which extends downwards as seen from the upper edge of the console 6 . Since the console 6 is manufactured from boron steel, the boundary between the hardened part 19 and the non-hardened part of the console 6 can be made extremely sharp, in the order of size of 10 mm.
  • the threshold at which the console 6 will start to be deformed while absorbing energy can be set by dimensioning the console 6 , especially as regards the position and size of the hole 15 . When this limit is reached, a bending will thus take place, i.e. a deformation in a controlled manner while energy is absorbed.
  • the spring attachment 9 consists of a cast element which can withstand extremely large forces. In this manner, a counteracting part is defined, by means of which large forces against the crossbeam 7 can be absorbed. Practical experiments have shown that forces of up to 50 tons can be absorbed with this arrangement.
  • the present invention thus functions approximately as an energy-absorbing “hinge” without any actual moving parts, except for the lower part of each console 6 .
  • the present invention is not limited to the examples of embodiments described above and in the drawings, but can be varied within the scope of the appended claims.
  • the present invention can in principle also be used as an underrun protection which is arranged at the rear end part of the vehicle or along its sides.
  • the amount of energy-absorbing consoles 6 can be one, two or more.
  • a correspondingly weakened portion can be obtained by shaping the waist 14 as a portion which is considerably thinner that the rest of the console 6 .
  • the console 6 can also be designed using two (or more) pieces of material with different properties and varying degrees of rigidity, which are joined to each other in a suitable manner.
  • the present invention can also comprise some other type of force-absorbing counteracting part.
  • a counteracting part can also be completely omitted.
  • each of the chassis consoles 4 can in principle be omitted.
  • the bumper 5 and the crossbeam 7 can be attached directly to the deformable console 6 .
  • such a chassis console 4 can advantageously be utilized in many kinds of vehicles for attachment of, for example, the bumper and cab of the vehicle.
